CARING for her bouncing baby son Roman seems to have inspired millionaire Cecil Chau's exotic wife Terri in a creative sort of way. Meeting her at yesterday's opening of Cafe Cova at Swire House she told us that she will soon be launching her own line of baby clothes under the label Ciao Baby. Terri was to have opened her first shop in one of Cecil's buildings. But you know how the property market is like these days, hubby has since sold the place. ''I would like to be at Pacific Place, but there is a two-year waiting list for space,'' moaned Terri.
